[Strange phenomena, mind games, suspense, uncovering the rules of each phenomenon, understanding and resolving them within those rules]
[The protagonist must observe and discover the rules for himself! Uncover the strange phenomena!]
Even though I'm the only guy in my class, my life isn't exactly blissful,
because there's something off about all these female classmates!
Her head falls on the ground, and while telling me she loves me, she asks me to pick it up for her. Does that seem normal?
Just because she called my name on the bridge and I didn't answer, she strangled me to death!
And then there's the one who mistook a boy for a person instead of a cat, and slashed his carotid artery with her claws.
Does any of this seem normal?
